windows closed, antenna down, make sure there arent any items "growing" from the subject, like a tree or telephone pole or sign. give the car a nice detailing.
infill lighting if there are details on the car that dont really show up (grill, emblem, body line) use a cheap reflector (cardboard with aluminum foil on it) to achieve this.

umm, polarized filter to reduce glare....

umm....
im no photographer, but thats what i've picked up from working WITH photographers.

If its dark, bring a tripod.
If its a 3/4 shot, turn the wheels so more wheel is shown, not the other way around.
Your light source should be behind you, even if that means you have to move your car for every picture.
Get photoshop and learn to use it.
windows should be all the way down or all the way up.
Make sure there's no light poles or trees behind your car.
Dont post 20 versions of the same veiw of your car, one is enough.
Take a lot of pictures, if its blurry at all, dont bother using it.
Get photoshop and learn to use it.
Taking all your pictures at stupid angles is not artistic, its just annoying.
Make sure the surroundings arent distracting.

I just remembered a really good tip for shooting at night that you all should know, but it really only works well if you have a buddy with you.
When taking a picture of your car at night/in the dark, dont leave the headlights on, it will usually look terrible and look like they're super bright. But, if you have a buddy, have him get in the car and quickly turn on the lights for like a 1/2 second while you take a long exposure. This way, the headlights are on like you wanted and you can still see the surrounding car.

Also, what kind of camera do you have? Not saying you need an $800 SLR and a $1500 lens, but if you're using some cheapie point and shoot, your pictures aren't going to come out very good.

I shot these with a Canon Powershot S2is

The one of the Mustang and the one of the Volvos was handheld, the others were with a tripod. I'm no photographer, but I know quality equipment helps ensure quality product. And, as was said, if you're taking pictures for the express purpose of a photo shoot, take tons of pictures. A little harder on the wallet if you're shooting film, but digital is great for that. Keep the ones you like, the rest go into the recycle bin.

Break photographic rules once in a while, show the tread on your tires, tilt that horizon...or even give it a 45* tilt! UPSET PEOPLE! IT'S A BLAST!!! Overexpose it for a crazy look, shoot into the light for a sillhouette.

Most of all though, location, it doesnt matter if you have a $50 point and shoot or a $1500 SLR-Lens combo, a driveway or parking lot shot is boring.

Night shots, you'll want a tripod, try to stay away from using the flash as you'll get shots like this, and you lose depth and quality of color

You want the ISO on the camera set as low as possible, plus a long exposure (shutter speed open) A/F set around 5-7 depending on lighting in the area, it doesn't necessarily need to have a long exposure, but i use anywhere from 8-15 second exposures, depending on lighting (longer exposure = more lighting hitting and entering the lens

You can see this shot is slightly blurry, GIMP can sharpen up the picture to a certain point before it starts getting grainy

1. FOR THE LOVE OF ****ING GOD KEEP YOUR CAMERA LEVEL TO THE GROUND.
2. Avoid the 'temptation' of HDR. Avoid it like the plague. I make no judgements as to anyone's ability with a camera, but 99% of all attempts at HDR look like ****. This is not me exaggerating. 99%. ****. If you think you need jump on a dumbass bandwagon to make your photos look good, then you also need a ****ing baseball bat to the head.

Find a good location to take a picture of the car, and take pictures from angles where there is a good contrast of background scenery but still have the focus on the car. Places with graffiti on walls, the beach, buildings with neat architecture, lots of trees, factories, warehouses and scenic parks are cool places. The Wal Mart parking lot is not.

This one would have been better if it wasnt so dark. Also, there is two cars present, which means you can do the cool trick I mentioned earlier about having the second person flick the lights on for about 1/2 second. If you have too, take two pictures so your buddy can do the lights in each vehicle, then just splice the pictures together.
